How does agl do their billing? I live in an apartment block with 20 one bedroom apartments all identical to each other all with the same appliances and all with agl. How ever we discovered we are all being charged different rates for our electricity and gas. One particular person isn't even paying a supply charge yet my latest bill is still $200 more then his, did I mention our flats are identical exactly the same appliances. When I asked agl to explain how my bill tripled in price I was told by customer service we are in colder months and every one has to use a heater. Funny considering agl called me to ask what electrical and gas run appliances I had so they could work out my billing suddenly electricity prices dropped and gas went through the roof. How does agl work out the bills. Do you just make up a price for each customer why is my gas bill 3 times more than the fellow across the road who runs his heater 24 hours a day. Why is agl charging us all different amounts?
